Abstract

A left mandibular toothplate of a chimaeroid fish collected from the Toolebuc Formation (Early Cretaceous, Albian), central Queensland is described. Comparisons with other chimaeroid genera show the toothplate to be sufficiently distinct to warrant the erection of a new genus. Ptyktoptychion tayyo gen. et sp. nov. is distinguished by the size and shape of its three tritors, the form of the symphysial facet and the overall shape of the toothplate.
